provements in Resilient Heels, ot' which the following is a specification.

This invention relates to an improvement in resilient heels, and has particular refer-V ence to that type of heel or lift which may be attached to the shoe without the use ofv cement, yet retains all of the advantages derived by the use of such cement.

An object of the invention is to provide a l5 heel lift which is so shaped, that when same. is nailed on the shoe will bind tightly against.

said shoe, to 'thereby exclude all foreign matter such as Water etc. As is well known Water getting between" the leather heel' and the rubber heel causes the nails to rust and thereby loosens the heel. i

A further object of the invention is to provide such a heel which embodies in its constructiona special form of washer, which when the heel is attached tothe shoe` will be forced into a reverse bend, such action in turn forcing a section of the upper surface of the heel into Contact with the leather heel.

A further object of the invention is/to proa vide a heel of the above mentioned character which is provided witha groove in its upper surface, which conforms to the line ot washers and nails, such groove acting as a'suction cup for additionally holdingthe heel against theshoe when the same is applied..

' A further object of the invention vis to provide such a heel which embodies all ol"v the advantages of the heels now in use, is extremely simple in construction, strong. duw rable and highly convenient in use. I

Otherimportantobjects and advantages of the invention will be apparent during the course of the following description.

Referring to the drawings, Figure l is a perspective view of e licei constructed in accordance with the invention, Y

Figure Q is a plan view thereof, Figure 3 is a front edge view, a. part being il shown in section, and before the heel has been nailed up,

Figure 6, is a perspective viewof.l the washer associated `with thielieelf 'ln the draw-1 ugs wherein like numerals are employed .to designate like parts throughout,

the numeral l0 designates-the heel'as a whole, having a concave upper surface ll and a convex lower surface 12;.Formed a suitable4 distance Jfrom -the edge of the heel and in `the `4upper 'su-.rtace,,is fan .arcuate groove 13.- This grooveis so curved asl to conform tothe line.Y of nails employedfto nail'the heel upon the shoe. A recess lftis formed inthe heel neargthe frontedge of the upper sur-face, and in a position to over.

lie the poi-nt at which the center na'ilsWill be` placed. ltwill lbe observed,v that neither thev groove nor the 'recess .communicate withthe outer edges of the heel. The ends of the groove are spaced a suitable distance from the t'ront edge of the heeh so that whenthe heel is trimmed on the shoe, the groove will not be cut into.

Molded `into the heel at the time of manufacture` are a plurality of washers 15, which washers areformed cup-shaped and are provided with holes i6 for the recegftion ot nails 1T employed inattaciiing-the heel Before the heel is applied, rthe washers lie in a position as illustrated inl Figure 3, and are yWhen the heel is nailed up. the heads of the nails will engage the lower sur-face ot the washers, as shown; The usual nail set. is employed to set the naiis uptight and will torce said washers topartalte ot a cup shape in the opposite direc-. tion. it will be obvious that` when suchaction takes place, fthef rubber adjacent the tops of the washers will be firmly pressed against 'the heel of the shoe. As shown in Figure 5, when the heei is attached `the washers wil force the centrai part of the lgroove 13 to bind against the heel. This leaves a slight space which actsI as a suction groove to further assist l'in holding the'heel lo the shoe, and to further prevent foreign matter from entering between the shoe and the heel. The lpurpose of providing1 the recess 14 is to give an additional binding point at the front of the heel. i

n operatomwhen it is desired to apply a heel to a shoe, such heel is positioned as illustrated in Figure 3. The nails are then driven in as usual, and forced uptight so that the heel will lie upon the shoe as illustrated in Figure 5. rThe purpose in forming the kheel concave, is to give it an additional binding force. The washer may be formed of any metal sufiiciently soft to allow of bending. llf desired, same 'may be formed of flexible or spring material, but this is unnecessary to the proper operation of the *1nvention. To insure of the proper bending oit the washers, they are made sufliciently large to overlie the edges of the groove 13, so that when the nails are set, the washers having a solid bearing of rubber at their edges will be held against movement, while the central portions thereof will move upwardly due to the giving of the material of the groove.

'It will be obvious from the foregoing, that a heel has been provided which will be high ly successful in use, and one that has very slight chance of becoming loose.A To those familiar with rubber heels, the value of such an invention will be apparent. lt is an extreme nuisance to have a rubber heel come loose on the shoe, and this is .man times due to the fact that the washer pulls t rough the rubber. Itvr is the common practice today to apply heels without the use of cement, and it was with this purpose in mind, that applicant has provided a heel which will be held firmly upon the shoe Without the use of such cement. l

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred example thereof, but it is to be understood that various changes in the shape, size and arrangement ot nail holes being formed in the lower face of the. litt and in alignment with the said groove concavo-convex washers embedded in the material of the lift and inalignment with the said nail holes and said groove, the concave face of said washers lying adjacent the concave upper surface of the lift, said washers being of such material and thickness as to allow them to be inverted by the securing nails so as to force the material of the groove to bind tightly against the heel, a recess formed in the upper tace ofsaid lift adjacent the front edge and spaced there from, a nail hole being formed in the lower face of the lift and in alignment with the recess and ua washer of concave-convex formation embedded in the material of the lift and in alignment with the recess and the last named nail hole, said washer when forced upward b the securing nail binding rhelmaterial of t e recess firmly against the ree 2. heel lift formed of resilient material, and provided with an arcuate groove in its upper. surface extending along its back and sides and terminating short of the front edge, a plurality of nail holes being formed in the lower face ofthe lift and in alignment with the said groove, concavo-convex -washers embedded in the material of the lift,

and in alignment with said nail holes and said groove, the concave face of said washers lying adjacent the upper surface `o the lift, said washers being of such material and thickness as to allow them to be inverted by the securing nails so as to force the mate rial of the groove to bind tightly against the heel, a recess formed yin the upper face of the lift adjacent the front edge and spaced therefromva nail hole being formed in the lower face of Vthe lift and in alignment with the said recess and a washer or concave-convex formation embedded in the material of the litt and in alignment with the recess and the last named .Y nail hole, 'said washer when forced upward b i' the securing nail, binding the material of the recess firmly against the heel.
